2 Claims.

1 My invention relatesto improvements in end guides for rug rollingmachines.

The object of my invention is to provide a device that will guide theends of rugs tokeep the rugs from creeping while being rolled betweenrollers.

Another object of my invention is to provide a device of the characterdescribed that will center itself so as to be in direct alignment withthe rug while it is being rolled.

Still another object of my invention is to provide a device that may beretrieved from contact or brought into engagement with the ends of therug simultaneously and evenly at both sides.

Another object of my invention is to provide a device that isconstructed in a manner to eliminate interference during the applicationof a wrapper on the outside of the rolled rug.

A still further object of my invention is to provide a device that isadaptable for use as an accessory to an existing rug rolling machine.

It is manifest to anyone familiar with the art of rolling rugs on amachine such as covered by my Patent No. 2,215,174 and by myimprovements covered by my pending application, Ser. No. 777,754, filedOctober 3, 1947, now Patent No. 2,573,188, dated October 30, 1951, thatit is advantageous to guide the end of the rug being rolled so as toprevent it from creeping-in the rolling operation. It isimperativehowever, to provide a device that will not interfere with therollers and as the diameter of the rolledportion of the rug increases itis necessary to raise, the end guides in proper proportion to thediameter of the rolled rug, and keep it in alignment with the center ofthe rug being rolled. Then too, the arrangement must be such as toprevent interference with the paper employed as an outer wrapper tocover the peripheral surface of the rolled rug.

The device specified, illustrated and claimed herein provides all theserequisites in an efiicient manner at a nominal cost of construction, andin a way to permit ready adaption to any existing equipment.

Other and further objects of my invention will become more apparent asthe description proceeds and when taken in conjunction with the drawingsin which:

Figure l is a fragmentary cross-sectional view of one end of the rugrolling machine showing the device in an engaged position and contactingthe end of the rug as it is being rolled.

Figure 2 is a similar view with the device engaging the one end of a rugthat is rolled completely, and is encased in a paper sheet extend ingoutward from the edge of the rug.

Figure 3 is a fragmentary cross-sectional view of the device asshown inFigures 1 and 2 and.

outwardly extending flanges mounted on a shaft H, which is journaled inbearings i2,and which bearings are slidably guided in a verticallydisposedslot I3 within the frame member [4 mounted onto a base forming apart of the assembled machine. The roller I0 is brought downward towardsthe rollers l5 and I5 by gravity and is arranged to be raised by the rugshown as It, as it is being rolled to a cylindrical shape by means ofcontact with the flanges on the rollers l9, l5 and I5. There is alsoshown a piston and cylinder arrangement I! which is employed to raisethe roller l0 above the rolled rug l6 when the rug is completely rolledand is to be ejected from the machine. 7 i

The bracket l8 attached to the side of the frame M has a pair ofvertically disposed apertures [9 arranged for slidably supporting a pairof vertical rods 20 which are equipped with bearings 2| at their upperends. A slidable shaft 7 member 22 is shown engaging the bearings 2i andextending horizontally in alignment with the rollers ill, l5 and I5. Theinner end of the shaft 22 is equipped with a disc 23 having a convexface, and rotatably attached to the shaft 22 by means of the hub member24. The shaft 22 is also equipped with a pulley member shown as 25 whichis slidably attached to the shaft 22 at a point between the bearings 2|and the outwardly depending end of the shaft 22 is provided with a pin26 which extends outward therefrom and engages an elongated slot 27 in alink member shown as 28, which is hingedly supported and pivoted at 29to an outwardly extending member 30 forming an integral portion of thebracket l8. The lower end of the link member 28 is pivotally attached toa piston rod 3| forming a part of a piston and cylinder assembly shownas 32 which may be hydraulically or pneumatically operated and which issupportedon the base shown as 33 which also forms an integral portion ofthe bracket 3.

There is an outwardly extending member 34 shown attached to the frame Mat its extreme upper end. This member is provided with an attachingmeans 35 to support one end of a cable 36 disposed on the outerperipheral surface of the pulley 25 and which has its other endrotatably attached at 37 to the inwardly extending end of the shaft Hwhich supports the top roll Hi.

In operation the device functions as follows:

The rug [6 is fed between the three rollers I 0, I5 and I 5' and iscaused to assume a radial contour to form the base of the rolled rug l6,

and as the diameter of the rolled rug increases it will cause the toproller Hi to rise upward by the sliding action of the bearings I2 withinthe vertical slot l3 in the frame 14.

When the rug I6 is inserted and the rolling operation is started, thepiston and cylinder mechanism 32 is brought into operation, and asvacuum is applied to the cylinder in the pneumatic operation, it willcausethe piston tobe retrieved, thereby actuating the linlrZBv andforcing the shaft 22inward so that the disc 23 contacts the edge of therug I 6, and as the diam eter of the rolled rug increases the top rollI0 will be raised, thereby causing the cable attached to the end of theshaft H to draw the pulley 25 upward and raise the shaft 22 in properratio, to maintain alignment of the shaft 22 with the center or core ofthe rolled rug l6. It is manifest, of course, that this arrangementapplies to both ends of the rug and is attached to both ends of themachine. It can be operated simultaneously with one source of pneumaticor hydraulic power.

Obviously, the paper wrapping shown as 38 is wider and extends outwardfrom the end of the rug [6, and the discs 23 are of a diameter somewhatsmaller than the diameter of the finished rolled rug so that the discs23 d8 not interfere with the application of the paper 38. After theoperation of the rolling and wrapping is completed the pistons are againbrought into operation and force the piston rods 3! outward from thecylinders and will bring the link levers 28 into position as shown inphantom in Figure 2, thereby causing the discs 23 to be brought out ofthe Wrapper and permitting the rug to be removed fromthe machine by the.action of the piston and cylinder arrangement I? working on the lever39.

In the chosen embodiment of my invention there are features notheretofore described in the prior art, and although I have shown aspecific arrangement of the component parts constituting my device, I amfully cognizant of the fact that many change in the form andconfiguration of these component parts may be made without effectingtheir operativeness, the spirit of my invention or the scope of theappended claims.

Having thus described my invention, what I claim and desire to secure byLetters Patent in the United States is:

1. A device of the character described to be used in combination with arug rolling machine having a pair of horizontal bottom rollers and a topadjustably and rotatably mounted roller,

the form of a cable, attached at one of wits ends.

to said base, said cableextending around said horizontal shaft andattached at its other end to said vertical adjustable top roller.

2. A device of the character described to be used with a rug rollingmachine having two rotatably mounted bottom rollers and a verticallyadjusted top roller, rotatably mounted on a base, a frame supported bysaid base, said device comprising vertically adjustable bearings mountedon said base, a pair of horizontal shafts slidably mounted within saidbearings in direct alignment with the point of contact of said toproller with said bottom rollers, means for moving said shaftshorizontally, each of said shafts being equipped with a vertical disc onits inwardly disposed end, said horizontal shafts being equipped withrotatable pulleys, and cable means attached at one end to said frame andthe other end to said top roller, said cable being disposed over thepulley on said horizontal shaft, thereby causing said horizontal shaftto be raised and loggered with the raisingand lowering of said top roer.
